The lakes were additionally characterised by environmental drivers and eutrophication proxies. Following a site specific approach including a validation procedure, a fish index including two abundance metrics catch per unit effort expressed as fish number and biomass and one functional metric of composition abundance of omnivorous fish was developed. Correlated with the proxy of eutrophication, this index discriminates between heavily and moderately impacted lakes. Additional analyses on a subset of data from Nordic lakes revealed a stronger correlation between the new fish index and the pressure data. Despite an uneven geographical distribution of the lakes and certain shortcomings in the environmental and pressure data, the fish index proved to be useful for ecological status assessment of lakes applying standardised protocols and thus supports the development of national lake fish assessment tools in line with the European Water Framework Directive. © 2012 Springer Science Business Media B.V. 704 Published version http //www.scopus.com/inward/record.url eid=2 s2.0 84873738235 partnerID=q2rCbXpz Articolo 2013_Hydrobiologia_704_193_211.pdf Articolo in rivista Kluwer 1573 5117 Hydrobiologia Dordr., Online Hydrobiologia Dordr., Online Hydrobiologia Dordr., Online Hydrobiologia.
